Design of High Performance 16-Bit Brent Kung Adder Using Static CMOS Logic Style in 45nm CMOS NCSU Free PDK. ... (or equivalently energy per bit).

Ken Shirriff has written up a great blog post about his reverse engineering of the Z80’s 16-bit increment/decrement circuit. The Zilog Z80 was one of the most popular microprocessors of the 70 ...

This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx.
